В FreeBSD 10 опцию WITHOUT_X11 в make.conf запретили и заменили на общее WITHOUT.
Вот так теперь система предупреждает админа при сборке порта:
/!\ WARNING /!\
You are using the following deprecated options: WITHOUT_X11
If you added them on the command line, you should replace them by
WITH="" WITHOUT="X11"
If they are global options set in your make.conf, you should replace them with:
OPTIONS_UNSET=X11
If they are local to this port, you should use:
misc_mc_UNSET=X11
Теперь в make.conf пишем так:
OPTIONS_UNSET=X11
